The adjustable clamp apparatus is able to fasten various type of life-saving buoy rings. Inside the waterproof chamber, electronic circuit boards, a power supply unit with batteries, a wireless signal communication module and antennas, various sensor modules and an electronic speed controller are wired together as a control unit. The hydro-driving mechanism is at the bottom of the adjustable clamp apparatus, which is connected with the control unit to actuate and control the movements. Wireless signals are transmitted and received between the control monitor and the control unit, allowing a rescuer to operate the water propelling device remotely to deliver a life-saving buoy ring over the surface of water toward the drowning person.

BACKGROUND OF THE INVENTION a) Field of the Invention

The invention is related to a life-saving device for propelling a buoy ring in the water. More particularly, the life-saving device is able to transport a floating object, such as a buoy ring or a foam noodle, rapidly over the surface of water to a drowning person who is waiting for helps. The advantages of the invention are to increase the efficiency of a rescue mission and to reduce the risks a rescuer or a lifeguard encountered.

b) Description of the Prior Art

When a drowning person in the water is calling for helps, the most important task for a lifeguard or a rescuer is to deliver a buoy ring or an object with buoyancy rapidly to the drowning person to grip and clamber about, and then to tow the drowning person out of the water as quickly as possible.

In general, a lifeguard will either swim, carrying a floating object, or throw out a buoy ring toward a drowning person. However, it consumes a lot of physical strength for the lifeguard to swim with a floating object against water resistance. In addition, it causes huge risks for the lifeguard to deal with the drowning person, such as to release grip and to free clutch of the drowning person. As to throwing out a buoy ring, there are limitations of accuracy in both the direction and the distance depending on different lifeguards and the circumstances of the rescue scene.

Accordingly, the abovementioned prior arts of rescuing a drowning person are rather unsafe, inconvenient and inefficient with many shortcomings to be improved.

SUMMARY OF THE INVENTION

The primary object of the invention is to provide a water propelling device for a life-saving buoy ring. The presented device can be fastened to various types of objects with buoyancy such as a standard buoy ring, a swim board or a foam noodle. Therefore, the floating object is able to be transported rapidly over the surface of water toward a drowning person who is waiting for helps by the invented water propelling device. The invention thereby is able to increase efficiency of the rescue mission and to prevent a lifeguard or a rescuer from encountering risks.

In order to achieve the abovementioned object, the invention discloses a water propelling device for a life-saving buoy ring which comprises three mechanical parts, an adjustable clamp apparatus, a waterproof chamber and a hydro-driving mechanism. A control monitor with a screen panel, or a mobile phone with control software installed, is used by a rescuer or a lifeguard to operate the water propelling device remotely. Three mechanical parts are connected together tightly to form a rigid structure.

The adjustable clamp apparatus is composed of an adjustable clamp holder, an upper clamp and a lower clamp. The main function of the adjustable clamp apparatus is to fasten firmly an object with buoyance between the upper and the lower clamps. The clearance between the upper and the lower clamps can be changed to suit various types of floating object such as a buoy ring, a swim board or a foam noodle by setting the opening of the adjustable clamp holder.

The waterproof chamber is mounted on the top of the adjustable clamp apparatus to ensure the waterproof chamber being above the surface of water at all times in a rescue mission. Inside the waterproof chamber, there are electronic circuit boards, a power supply unit and batteries, a wireless signal communication module and antennas, various sensor modules and an electronic speed controller wired together to actuate and control movements of the invented water propelling device with the fastened floating object in the water. The command and response signals are exchanged wirelessly between the remote operating rescuer through the control monitor or the mobile phone and the waterproof chamber.

The hydro-driving mechanism is fixed to the bottom of the adjustable clamp apparatus to ensure the hydro-driving mechanism being submerged in the water at all times in a rescue mission. In addition, the hydro-driving mechanism is connected to the electronic speed controller inside the waterproof chamber by electric cables to provide a propeller function, for moving forward and backward, and a rudder function, for turning directions. The propeller function and the rudder function work together harmoniously enabling the invented water propelling device with the fastened floating object to perform movements in the water.

As a result, to rescue a drowning person calling for helps, a rescuer or a lifeguard fastens an object with buoyance available in the rescue scene with the invented water propelling device first, and puts the device and the floating object together in the water. Then, the rescuer is able to deliver the floating object to the drowning person by operating the control monitor or the mobile phone which wirelessly connects with the invented water propelling device. The command signals from the control monitor are received by the wireless signal communication module and antennas, and are transmitted to the electronic boards for processing. The output signals for the propeller function and the rudder function are generated accordingly and sent to the electronic speed controller to actuate the hydro-driving mechanism. In the mean times, various sensor modules inside the waterproof chamber collect surrounding and status information during the rescue mission for the electronic boards to process. The output signals are sent to the electronic speed controller and the hydro-driving mechanism for feedback-control adjustment of movements, and to the wireless communication modules and antennas to transmit back to the control monitor or the mobile phone for the rescuer to supervise.

Therefore, to rescue a drowning person in the water by the invented water propelling device with a life-saving buoy ring is able to resolve the limitations of the distance and the direction of throwing out a buoy ring by different rescuers at different rescue scenes. In addition, the rescuer will be released from the risks of consuming physical strength and encountering resistance against the drowning person to accomplish a rescue mission safely and quickly.

To enable a further understanding of the said objectives and technical methods of the invention herein, the drawings below are followed by the detailed descriptions of the preferred embodiments.
